"Hamas claimed responsibility for rocket fire on Dimona, saying their target was the city's nuclear reactor," Ynetnews reported yesterday.
According to the Israel Defence Forces (IDF), more than 225 rockets were fired at Israel since Operation Protective Edge began late Monday night.
Some 40 of those rockets were intercepted by Israel's advanced Iron Dome missile interception system.
At least two rockets fell in open areas north of Zikhron Ya'akov, just 37 km south of Haifa, in what was the longest reaching rocket attack since the start of the Israeli offensive in Gaza.
Israel has two nuclear reactors, one at Dimona in the Negev desert, and the other at its nuclear research facility at Nahal Sorek, west of Jerusalem.
